Undermining security and weakening Android

I have Amazon Prime, I quite like their shows, and whenever I have some time to kill I’ll watch an episode or 3.

A couple of weeks ago, I thought it would be a good idea to install the official Amazon video app on my android device, so that I could download episodes and watch them when travelling. I previously had it on my iPad, so knew it worked well.

However, I wasn’t able to find the Amazon video app in the Google Play store. Perplexed, I went hunting, and quickly found that Amazon does indeed have an app for Android, only it isn’t on the official store.

Amazon helpfully has instructions on how to install the app on your Android phone or tablet from its own Amazon Appstore.

For those of you playing along at home, you may have spotted the obvious flaw in this approach.

To install the app, Amazon is advising you to “Go to your device’s Settings, select Security or Applications (depending on device), and then check the Unknown Sources box.)”

But there are others

Unfortunately, this isn’t isolated to Amazon. Ken Munro pointed out on twitter that the National Lottery also asks you to download its app from a dark alley in the back.

Although, to its credit, the National Lottery does mention to, “Remember to change your security settings back to your preferred choice.”

Quentyn Taylor pointed out that Samsung also does similar.

So what’s the big deal?

The official Google apps store isn’t a complete safe haven. Malicious apps have bypassed the security checks and ended up in the app store many times. Companies like Amazon, the National Lottery, or Samsung aren’t fly-by-night companies that will deliberately push out insecure apps; so what’s the harm in downloading the app and switching security back.

For most users that aren’t technically savvy, the ability for their Android device to block downloads from unknown sources is there to prevent them from accidentally downloading malicious software. – Strike one.

The security industry has spent a great deal of time and effort to educate users in the dangers of downloading unknown files from untrusted sources, and this approach undermines a lot of those efforts. – Strike two.

Normalising such actions enables attackers to try similar tactics. After all, if companies like Amazon have legitimised the approach of turning off security settings and downloading apps from their own environments, it is something that any company could emulate. – Strike three.

The reality is that convenience trumps security most of the time. Users will intentionally or accidentally bypass security controls to get the app of their choosing, often leaving themselves vulnerable in the process. Which is why it’s important that manufacturers, providers, app stores, and everyone in between work together to help deliver a secure experience to users, instead of elements working against each other.
